chrome.debugger

Description:

The chrome.debugger API serves as an alternate transport for Chrome's remote debugging protocol. Use chrome.debugger to attach to one or more tabs to instrument network interaction, debug JavaScript, mutate the DOM and CSS, etc. Use the Debuggee tabId to target tabs with sendCommand and route events by tabId from onEvent callbacks.

Availability:

Since Chrome 18.

Permissions:

"debugger"

Notes

As of today, attaching to the tab by means of the debugger API
and using embedded Chrome DevTools with that tab are mutually exclusive.
If user invokes Chrome DevTools while extension is attached to the tab,
debugging session is terminated. Extension can re-establish it later.

Manifest

You must declare the "debugger" permission in your extension's manifest
to use this API.
